CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 61/948,523, filed Mar. 5, 2014, which is hereby incorporated by reference in its entirety as though fully set forth herein.

TECHNICAL FIELD

This instant disclosure relates generally to an apparatus for connecting a baluster to a rail of a railing and/or a fence.

BACKGROUND

Conventional railing designs often require a discrete fastener, such as a bolt or a screw to connect a baluster to a rail or a fence. Relative to a design that does not require a discrete fastener, assembling and/or manufacturing railings or fences that require such discrete fasteners may require additional time, cost, and/or effort, which may be associated with centering components, measuring distances between balusters, locating drilling locations, drilling holes, and/or driving fasteners into the holes. A design that may eliminate and/or simplify one or more of the above activities from an assembly process may be desirable.

Conventional railing designs are often directed only to configurations in which balusters are disposed at a single angle relative to a rail, such as entirely perpendicular to a rail. A design that may be capable of accommodating more than one angle may be desirable.

SUMMARY

The present disclosure includes a railing that may include first and second rail portions, a baluster, a cover, an insert, and/or a swivel connector. A swivel connector may be retained by a rail portion and a cover, and/or may be retained by an insert and a rail portion, and the retaining may be accomplished without the use of a fastener.

In embodiments, a railing assembly may comprise a first rail portion including a first aperture, a second rail portion including a second aperture, a first swivel connector disposed in the first rail portion and extending through the first aperture, a second swivel connector disposed in the second rail portion and extending through the second aperture, and/or a baluster. The baluster may be secured to the first rail portion via the first swivel connector and may be secured to the second rail portion via the second swivel connector.

In embodiments, a swivel connector for a railing assembly may comprise a swivel connector body that may include a first side wall, a second side wall disposed opposite the first side wall, a curved third side wall disposed between and perpendicular to the first side wall and the second side wall, and/or a planar fourth side wall disposed perpendicular to the first side wall and the second side wall.

Referring to FIGS. 1 and 2, a railing assembly 10 may include a swivel connector 20 _(N), an insert 40, a baluster 60 _(M), a first rail portion 70, a second rail portion 80, and/or a cover 90.

In embodiments, railing 10 may include one or more swivel connectors 20 _(N) that may include a body having a first side wall 22 _(N), a second side wall 24 _(N), a third side wall 26 _(N), a fourth side wall 28 _(N). For example, and without limitation, railing 10 may include swivel connectors 20 ₁, 20 ₂, 20 ₃, 20 ₄, 20 ₅, 20 ₆. Swivel connectors 20 ₁, 20 ₂, 20 ₃, 20 ₄, 20 ₅, 20 ₆ may include first side walls 22 _(k), 22 ₂, 22 ₃, 22 ₄, 22 ₅, 22 ₆, second side walls 24 _(k), 24 ₂, 24 ₃, 24 ₄, 24 ₅, 24 ₆, third side walls 26 _(k), 26 ₂, 26 ₃, 26 ₄, 26 ₅, 26 ₆, and/or fourth side walls 28 _(k), 28 ₂, 28 ₃, 28 ₄, 28 ₅, 28 ₆, respectively. A swivel connector 20 _(N) may be configured as a single, unitary component.

In embodiments, a swivel connector 20 _(N) may include one or more of a variety of shapes, sizes, and/or configurations. For example, and without limitation, a swivel connector 20 _(N) may include a generally cylindrical shape and/or may include a generally planar side wall, such as fourth side wall 28 _(N). Fourth side wall 28 _(N) may be configured such that a portion of swivel connector 20 _(N) may be squared and/or leveled off and/or may be configured such that a shape of swivel connector 20 _(N) may generally resemble a partially filled cylinder.

In embodiments, first side wall 22 _(N) and second side wall 24 _(N) may be disposed generally parallel to each other and/or may be spaced from each other. Third side wall 26 _(N) may be disposed generally perpendicular to first side wall 22 _(N) and/or second side wall 24 _(N), and/or may be curved and/or at least partially curved and/or arced. In embodiments, fourth side wall 28 _(N) may be disposed generally perpendicular to first side wall 22 _(N) and/or second side wall 24 _(N). Fourth side wall 28 _(N) may be generally planar and/or may connect first end 26A_(N) (e.g., first ends 26A₁, 26A₂) and second end 26B_(N) (e.g., second ends 26B₁, 26B₂) of third side wall 26 _(N).

In embodiments, first rail portion 70 and/or second rail portion 80 may include one or more of a variety of shapes, sizes, and/or configurations. In embodiments, first rail portion 70 and/or second rail portion 80 may include lengths 70A, 80A, first ends 70B, 80B, second ends 70C, 80C, and/or longitudinal axes 70D, 80D. First rail portion 70 and/or second rail portion 80 may include a generally U-shaped cross section. Lengths 70A, 80A may generally correspond to a length of a section of a railing 10. For example, and without limitation, lengths 70A, 80A may be about six feet long and/or may be about eight feet long.

In embodiments, a baluster 60 _(M) (e.g., balusters 60 ₁, 60 ₂, 60 ₃, 60 ₅, 60 ₆, 60 ₇) may be configured to extend between first rail portion 70 and second rail portion 80. Baluster 60 _(M) may include one or more of a variety of shapes, sizes, and/or configurations. Baluster 60 _(M) may include portions that may be generally solid and/or may include portions that may be generally hollow. For example, and without limitation, baluster 60 _(M) may include an generally hollow and elongated rectangular shape (e.g., a rectangular prism), a generally hollow and elongated cylindrical shape, and/or an irregular shape. Baluster 60 _(M) may include a height 60D that may correspond to (e.g., may be greater than) the distance between the first and second rail portions 70, 80. Balusters 60 _(M) may include longitudinal axes 60A_(M) (e.g., axes 60A₁, 60A₂, 60A₃). In embodiments, each baluster 60 _(M) may include a width 60B, and/or a length 60C, which may or may not be the same. In embodiments, a baluster 60 _(M) may include a rectangular, square, annular, and/or rounded cross-section (e.g., if viewed along a longitudinal axis 60A_(M)). In embodiments, it may be desirable to connect a baluster 60 _(M) to first rail portion 70 and/or second rail portion 80.

In embodiments, swivel connector 20 _(N) may include one or more projections 50 _(N). Projections 50 _(N) may be configured for connecting a baluster 60 _(M) to a rail portion (e.g., first rail portion 70 and/or second rail portion 80). Projections 50 _(N) may include one or more of a variety of shapes, sizes, and/or configurations. For example, and without limitation, projections 50 _(N) may include a generally cylindrical shape that may extend from third side wall 26 _(N). Projections 50 _(N) may or may not extend between planes of first side wall 22 _(N) and second side wall 24 _(N). Projections 50 _(N) may include a height 50A and/or a width 50B. In embodiments in which projections 50 _(N) may be generally annular and/or cylindrical, width 50B may correspond to a diameter of the projection 50 _(N). Width 50B may generally correspond to width 60B of baluster 60 _(M). Height 50A may correspond to a desired amount of retaining force between a projection 50 _(N) and a corresponding baluster 60 _(M). For example, a height 50A that is relatively tall may correspond to a greater retaining force and/or a height 50A that is relatively short may correspond to a smaller retaining force. In embodiments, all projections 50 _(N) may be of substantially the same size and/or at least one projection may be of a different size than at least one other projection.

In embodiments, projections 50 _(N) of swivel connectors 20 _(N) may include one or more ribs 52 that may be arranged vertically and/or horizontally. Ribs 52 may be configured to increase width 50B of a projection 50 _(N) and/or provide a press fit and/or interference fit between the projection 50 _(N) and a corresponding baluster 60 _(M). An outer diameter of ribs 52 may be at least as large as an inner dimension (e.g. length and/or width) of a corresponding baluster 60 _(M). A press fit and/or interference fit may provide a connection between the baluster 60 _(M) and the projection 50 _(N) that may be permanent and/or semi-permanent. For example, and without limitation, a press fit and/or interference fit may permit the baluster 60 _(M) to be initially pushed onto and/or connected to the projection 50 _(N), and/or may prevent and/or limit subsequent movement of the baluster 60 _(M) in at least one direction (e.g., along axis 60A_(M)). A press fit and/or interference fit may allow for connection of a baluster 60 _(M) with a rail portion (e.g., first rail portion 70 and/or second rail portion 80) without the use of fasteners and/or tools, such as, for example, a screw, a bolt, a screwdriver, and/or a wrench. In embodiments, ribs 52 may be disposed around an axial middle portion of projections 50 _(N) and/or projections may include one or more axial portions (e.g., top and/or bottom axial portions) that do not include ribs 52 that may be at least as large, in combination and/or individually, the axial middle section having ribs 52.

In embodiments, swivel connectors 20 _(N) and/or projections 50 _(N) of swivel connectors 20 _(N) may be spaced from each other and may be spaced equally and/or unequally. In embodiments, the spacing between projections 50 _(N) may depend upon the orientation of one swivel connector 20 _(N) relative to another swivel connector 20 _(N).

In embodiments, the spacing of swivel connectors 20 _(N) may correspond to compliance with legal requirements, such as federal, state, and/or local building codes, that may set forth requirements regarding spacing of balusters 60 _(M). Additionally or alternatively, in embodiments, swivel connectors 20 _(N) may be spaced to correspond to and/or align with apertures (e.g., apertures 78, 88) in a rail portion (e.g., first rail portion 70 and/or second rail portion 80). Aligning apertures 78, 88 with swivel connectors 20 _(N) may permit at least a portion of a swivel connector 20 _(N), which may include a projection connecting portion/element 30 and/or a projection 50 _(N), to extend through apertures 78, 88 and/or to connect with a baluster 60 _(M).

In embodiments, a swivel connector 20 _(N) may include a projection connecting portion 30 that may be configured to connect swivel connector 20 _(N) with a projection 50 _(N). A projection connecting portion 30 may include one or more of a variety of shapes, sizes, and/or configurations. Projection connecting portion 30 may extend generally perpendicularly from fourth side wall 28 _(N) and/or may include an enlarged portion 30A that may be larger (e.g., include a larger width and/or diameter) than the rest of projection connecting portion. Enlarged portion 30A may be disposed at an end 30B of projection connecting portion. Enlarged portion 30A may be configured to retain a projection 50 _(N). For example, and without limitation, enlarged portion 30A may be configured such that a projection 50 _(N) may be initially pushed onto projection connecting portion 30 and/or may be configured such that if a projection 50 _(N) is pushed onto projection connecting portion 30, projection 50 _(N) may not be able to move and/or may be resistant to moving in at least one direction (e.g., a direction away from swivel connector 20 _(N)).

In embodiments, more than one swivel connector 20 _(N) may be disposed in and/or inserted into a rail portion (e.g., first rail portion 70 and/or second rail portion 80). In embodiments, the number of swivel connectors 20 _(N) inserted into a rail portion 70, 80 may correspond to the length of the rail portion.

In embodiments, such as generally illustrated in FIG. 4, first rail portion 70 and/or second rail 80 portion may include a first side wall 72, a second side wall 74, and/or a third side wall 76. In embodiments, second rail 80 portion may include a first side wall 82, a second side wall 84, and/or a third side wall 86. Side walls 72, 74, 82, 84 may include one or more protrusions. For example and without limitation, first side wall 72 may include first protrusion 72A, second protrusion 72B, third protrusion 72C, fourth protrusion 72D; second side wall 74 may include first protrusion 74A, second protrusion 74B, third protrusion 74C, fourth protrusion 74D; first side wall 82 may include first protrusion 82A, second protrusion 82B, third protrusion 82C, fourth protrusion 82D; and/or second side walls 84 may include first protrusion 84A, second protrusion 84B, third protrusion 84C, fourth protrusion 84D.

In embodiments, first rail portion 70 and/or second rail portion 80 may include a generally U-shaped configuration, which may open away from the other of first rail portion 70 and second rail portion 80.

In embodiments, first side wall 22 _(N) and/or second side wall 24 _(N) of swivel connector 20 _(N) may be configured to cooperate with a rail portion, such as, for example, first rail portion 70 and/or second rail portion 80. As generally illustrated in FIGS. 1-5, a length 22A of the longest portion of first side wall 22 _(N) and/or a length 24A of the longest portion of second side wall 24 _(N), either or both of which may generally correspond to a diameter of swivel connector 20 _(N), may correspond to the length 78B of aperture 78 and/or correspond to the length 88B of aperture 88. For example, and without limitation, length 22A and/or length 24A, which may or may not be equal, may be longer than lengths 78B, 88B, which may at least help hold swivel connector 20 _(N) in a particular lateral position and/or prevent all of swivel connector 20 _(N) from passing through aperture 78 and/or aperture 88.

In embodiments, such as generally illustrated in FIGS. 2-4, first rail portion 70 and/or second rail portion 80 may include one or more apertures, such as, for example, apertures 78, 88. Apertures may be configured to receive at least a portion of a baluster 60 _(M) and/or may be configured to prevent and/or reduce rotation of a baluster 60 _(M) after the baluster 60 _(M) has been connected with a swivel connector 20 _(N). Apertures 78, 88 may include one or more of a variety of shapes, sizes, and/or configurations. In embodiments, the shape of an aperture 78, 88 may correspond to a shape of a baluster 60 _(M). For example, and without limitation, apertures 78, 88 may include a generally rectangular shape that may correspond, for example, to a baluster 60 _(M) having a generally square and/or rectangular cross-section. The dimensions of apertures 78, 88 may be configured such that if a baluster 60 _(M) is at least partially received in the aperture 78, 88, baluster 60 _(M) may not be able to rotate. For example, and without limitation, width 78A and/or width 88A of apertures 78, 88 may be substantially equal to width 60B of a baluster 60 _(M), and/or length 78B and/or length 88B of apertures 78, 88 may be substantially equal to length 60C of baluster 60 _(M).

In embodiments, such as generally illustrated in FIGS. 2-5, a protrusion of a rail portion side wall (e.g., protrusion 72A and/or protrusion 82A) may include a flange portion, such as flange portions 72E, 74E and/or flange portions 82E, 84E. Flange portions may correspond to recesses 42A, 44A of an insert 40 and/or to recesses 92A, 94A of a cover 90.

In embodiments, such as generally illustrated in FIGS. 1-5, railing 10 may include an insert 40. Insert 40 may be configured to cooperate with a rail portion, such as, for example, first rail portion 70 and/or second rail portion 80. In embodiments, insert 40 may include a side wall 40A that may be planar and/or snapping portions 42, 44 that may extend generally normal to side wall 40A. Snapping portions 42, 44 may include recesses 42A, 44A, respectively, that may correspond to flange portions 72E, 74E, 82E, 84E of side walls, 72, 74, 82, 84. For example, and without limitation, snapping portions 42, 44 may be configured to cooperate with first protrusions 82A, 84A of second rail portion 80. Insert 40 may be configured to slide into second rail portion 80 from first end 80B and/or second end 80C, and/or insert 40 may be configured to be pressed toward third side wall 86 into second rail portion 80 until flange portions 82E, 84E engage recesses 42A, 44A. For example, and without limitation, snapping portions 42, 44 may be configured to deflect upon being pressed into rail portion 80 until recesses 42A, 44A engage flange portions 82E, 84E. In embodiments, insert 40 may be configured to hold or help hold a swivel connector 20 _(N) in a particular location/orientation.

In embodiments, such as generally illustrated in FIGS. 1-5, a railing 10 may include a top profile, such as a cover 90. Cover 90 may include a first side wall 90A, a second side wall 90B, and one or more snapping portions 92, 94 that may generally extend from a center portion 90C of cover disposed between first side wall 90A and second side wall 90B. Snapping portions 92, 94 may include a recesses 92A, 94A that may correspond to flange portions 72E, 74E of side walls 72, 74. For example, and without limitation, snapping portion 92 may be configured to cooperate with first protrusion 72A of first rail portion 70 and/or cover 90 may be configured to be pressed into (e.g., vertically) first rail portion 70 until flange portions 72E, 74E engage recess 92A, 94A.

In embodiments, cooperation of insert 40 with second rail portion 80 and/or cooperation of cover 90 with first rail portion 70 may permit one or more swivel connectors 20 _(N) to be retained (e.g., axis 34 may not move) without the use of a fastener, such as a screw or a bolt.

In embodiments, a process of assembling a railing 10 may include inserting a swivel connector 20 _(N), with projection connecting portion 30 directed toward aperture 78, between first rail portion first wall 72 and first rail portion second wall 74 until third side wall 26 _(N) of swivel connector 20 _(N) contacts first rail portion third wall 76 and/or projection connecting portion 30 is disposed beyond third wall 76. If third wall 26 _(N) of swivel connector contacts first rail portion third wall 76 and/or projection connecting portion 30 is disposed beyond first rail portion third wall 76, a projection 50 _(N) may be pushed onto projection connecting portion 30 and/or a cover 90 may be inserted/snapped into first rail portion 70.

In embodiments, a similar assembly process may be used in relation to second rail portion 80. For example, a swivel connector 20 _(N), with projection connecting portion 30 directed toward aperture 88, may be inserted between second rail portion first wall 82 and second rail portion second wall 84 until third side wall 26 _(N) of swivel connector 20 _(N) contacts second rail third wall 86 and/or projection connecting portion 30 is disposed beyond second rail portion third wall 86. If third side wall 26 _(N) of swivel connector 20 _(N) contacts second rail portion third wall 86 and/or projection connecting portion 30 is disposed beyond second rail portion third wall 86, a projection 50 _(N) may be pushed onto projection connecting portion 30 and/or an insert 40 may be inserted into first rail portion 70.

In embodiments, swivel connector 20 _(N) may be configured to be disposed at least partially in a rail portion (e.g., first rail portion 70 and/or second rail portion 80) such that swivel connectors 20 _(N) are able to rotate and/or swivel about an axes 34 _(N) (e.g., axes 34 _(k), 34 ₂, 34 ₃, 34 ₄, 34 ₅, 34 ₆) that may be perpendicular to baluster axis 60A_(M), longitudinal axis 70D of first rail portion 70, and/or longitudinal axis 80D of second rail portion 80. For example, and without limitation, cover 90 may cooperate with first rail portion 70 to retain swivel connector 20 _(N) in lateral directions (e.g., axis 34 may not move) and/or may permit swivel connector 20 _(N) to rotate about axis 34. Additionally or alternatively, insert 40 may cooperate with second rail portion 80 to retain a swivel connector 20 _(N) in lateral directions (e.g., axis may not move) and/or may permit swivel connector 20 _(N) to rotate about axis 34. Rotation may permit swivel connector 20 _(N) and/or rail portions to accommodate disposing a baluster 60 _(M) at more than one angle relative to rail portions (e.g., not just at a right angle to rail portions 70, 80). Additionally or alternatively, rotation of swivel connector 20 _(N) may correspond to railing being rackable (see, e.g., FIG. 5). In embodiments, a swivel connector 20 _(N) may be configured to rotate up to or more than 45 degrees.

In embodiments, a swivel connector 20 _(N) may be disposed at least partially in first rail portion 70 such that swivel connector 20 _(N) is in frictional contact with a plurality of points.
